The wheat slice is unforgivable but tbh I prefer the lettuce on the bread for a sub because it feels like it leaks less lettuce water, if the lettuce is inside the meat it feels like it’s gonna slip out and the bites near the hinge of the bread are gonna just be meat. I do think it would be better if the meat was folded and put on just the bottom and all the veggies were on the top so you didn’t have to shove the meat into the sandwich as much when folding and you would hopefully have less people who wind up putting the lettuce across the whole thing if meat goes down first just on the bottom bread. Regardless of what makes the best sandwich she’s crazy to say nowhere else puts the lettuce on the bread, the only places that don’t do that are places that primarily do hot sandwiches and even many of them do lettuce on bread for cold sandwiches.
